We explore, mostly using data from solar neutrino experiments, the hypothesis that the neutrino mass eigenstates are unstable. We find that, by combining B8 solar neutrino data with those on Be7 and lower-energy solar neutrinos, one obtains a mostly model-independent bound on both the ν1 and ν2 lifetimes. We comment on whether a nonzero neutrino decay width can improve the compatibility of the solar neutrino data with the massive neutrino hypothesis.
